Abstract: The thermal head supporting device of the invention comprises a pair of positioning members disposed at both sides of a platen, a head press/release mechanism movable toward and away from the platen, and a head unit coupled with the head press/release mechanism. The positioning members are disposed coaxially with the platen. The head unit is formed of a head supporting member removably coupled to the head press/release mechanism with a predetermined play, a thermal head supported on the head supporting member and having a plurality of heating elements arranged in a straight line thereon and in confronting relationship with the platen, and a pair of engagement members attached to both sides of the thermal head adjustably for position, and each of the engagement members has a cutting formed therein allowing each positioning member to be removably fitted therein.

Abstract: A reading surface of a document is illuminated by a light source, and a light beam reflected on the reading surface is reflected on a reflecting mirror. Then, the reflected light beam is guided in such a direction as to pass in the vicinity of a light shielding plate for shielding the constitutional elements from the light. A lens is located near the light source at a position where the light beam guided in the above direction is allowed to pass. A shading correcting device is made up of a first shading correcting portion formed by a part of the light shielding plate and a second shading correcting portion formed in a body case for holding the constitutional elements. The shading correcting device is designed to restrict a more quantity of light of the light beam incident upon the lens at a portion nearer to an optical axis of the lens. A photoelectric correcting device is provided in a position where the light beam passing through the lens is focused.

Abstract: A ticket issuing device for a ticket machine according to the present invention comprises a holding plate for receiving thereon tickets fed one by one from a data writing station by a feeding mechanism and for temporarily holding the tickets in a layered condition thereon, a receiving plate located adjacent a ticket issuing port, and an operating member for discharging tickets on the holding plate onto the receiving plate when an issuing signal is issued. Thus, a plurality of tickets can be discharged at a time onto the receiving plate, thereby giving facilities to a person who tries to receive the tickets. The device further comprises a transferrer constituted by electromagnets, the holding plates, and a mechanism interconnecting them which operates when an issue stopping signal is issued to transfer tickets on the holding plate toward a storage. Thus, tickets to be withdrawn are automatically transferred into the storage, thereby giving facilities to a withdrawing person.

Abstract: The sheet supply device comprises a sheet stocker including a lifting table mounted for up and down movement with a large number of sheets accumulated in layers thereon which sheets are different in thickness between opposite sides thereof and a paper feed roller for contacting with an uppermost one of the sheets, a string having one end fastened to each of opposite sides of the lifting table corresponding to the opposite sides of the sheets providing the difference in thickness, a first take-up drum or drums located corresponding to the thicker side of the sheets and each having the other end of the string corresponding to the thicker side of the sheets fastened thereto, a second take-up drum or drums located corresponding to the thinner side of the sheets and each having the other end of the string corresponding to the thinner side of the sheets fastened thereto.
