Abstract: An analog input device including at least one mounting panel and a matrix of analog push button assemblies mounted thereon. Each analog push button assembly including an analog pressure sensor including a pressure reception arrangement having an optical sensing sub-arrangement configured to measure an amount of light varied according to a pressure sensed at the pressure reception arrangement and an output terminal for outputting an analog signal corresponding to the amount of light measured, and a plunger element configured to exert the pressure on the pressure reception arrangement. The analog input device may include a multiplexer including an input side coupled to the push button assemblies and an output side; an analog-to-digital converter coupled to the output side of the multiplexer; a processor coupled to the analog-to-digital converter and configured to output a data packet; and a communication interface configured to transmit the data packet to a host computing device.

Abstract: A printer has a lower module and upper module. The lower module has a paper feed unit and a printing unit. A back of the upper module is hinged to lower module. A paper handling part holds paper after printing by the printing unit. A discharge unit in the upper module moves the paper out of the upper module while maintaining a hold on a rear portion of the paper and to draw the paper back into the upper module after an elapse of time. A container includes a support member that rotates into contact with and moves away from a lower part of the upper module. The container configured to receive and store the paper that has been drawn back by the discharge unit. The paper is stored in a region between the support member and the lower part of the upper module.
