Abstract: In a counter mechanism of a feeding device, in each discrete feeding operation, an amount corresponding to single delivery unit of stored material is ejected and providing a simple construction and permitting the remaining amount of stored material in the device invisible from outside to be known by counting the number of delivered units of stored material. A counter mechanism of this invention comprises a fixed member (10) fixed to the body and having cam lobes formed in circumferential direction, a gear (20) having a count number display that can be monitored from the outside, a rotating member (40) being restricted to rotate either to a position in the rotating direction to allow feeding of a single delivery unit and a position to preventing feeding of the stored material, a ring member (30) which can rotates in interlock with the rotating motion of the rotating member and comprises a resiliently deformable cam follower having a jaw formed at a predetermined position in circumferential direction.

Abstract: In a display and input device (CP) displaying information on a display (DP) and performing changing of the information and communication through switch operating means (CSW1), the switch operating means (CSW1) are arranged on the left and right edges of the display (DP), opaque members among members forming the switch operating means (CSW1) are arranged outside the screen of the display (DP), and only transparent members are arranged on the display (DP). Thus, a switch operation can be performed while recognizing functions of the switch operating means (CSW1) and the switch operating means (CSW1) having the stroke feeling and click feeling of a mechanical switch so that an operating environment having excellent operability and implementing reliable input can be obtained.

Abstract: A push-button switch provided with a hollow push button, a case supporting it, and a switching mechanism having a first contact disposed within the case and a second contact disposed opposite to the first contact, with one of its ends being inserted into a hole of the push button. Within a hole formed in an inserted section of the switching mechanism, a slide block is provided slidably in a direction crossing the direction in which the push button is pushed. A slope capable of engaging with a slope of the hole of the push button is formed on the slide block. A coil spring (return spring) for energizing a shaft of the switching mechanism so as to abut the push button is provided on the bottom of the case. This configuration enables the push button to take up a first OFF state, an ON state and a second OFF state in order of depression.
