Filed: 1978-03-30
Abstract: PURPOSE: To return a next banknote inserted during discriminating process securely, by providing a plurality of banknote detection sensors and simple logic circuit.  
     CONSTITUTION: A banknote inserted into an inlet slit 4 is detected by detection sensors P 1 , P 1 ', and the transfer is started by normal rotation of a motor, then the authenticity of the banknote is discriminated 5. When the banknote reaches detection sensors P 3 , P 3 ', after discrimination, if the banknote is false, it is returned due to reverse rotation of the motor. When the banknote is genuine, it is transferred up to a coffer 6, then the motor stops. At the same time, the genuine banknote signal VE is outputted for a specified time. When a next banknote is inserted within this time, it is detected by detection sensors P 1 , P 1 ', or P 2 , P 2 ', so that the detection logic outputs P 01 , P 02  become 1. Therefore, through an OR circuit OR 1 , the output of an AND element AND 3  becomes 1, and a motor reverse rotation signal MR is generated through an OR element OR 3 . Thus, the banknote inserted while discriminating may be securely returned.

Title: Liquid crystal display device
Inventor: OKUBO YUKITOSHI
IPC: G02F1/133
Filed: 1986-02-21
Abstract: PURPOSE:To permit exact discrimination whether a measured information is in a normal range or in an alarm range by providing a first means for making a display segment area formed between a bent shaped end and another end variable, and a second means for making optical characteristics of transmitted light or reflected light of the display segment different. CONSTITUTION:Good conductive electrode sections 3a, 3b are in at least two separated regions of a resistance layer 3 on a substrate 2, and an electroconductive layer or resistant layer 5 is formed on a substrate 6. Planes of polarization of incident light I0 are aligned as regulated by the plane of polarization of a polarizing plate 1, and incided to a second polarizing plate 7 with an angle of rotation corresponding to torsional orientation of liquid crystal molecules when the light passes through the liquid crystal layer between the resistance layer 3 and the layer 5. When the plane of polarization in this stage forms 90 deg. to the plane of polarization of the polarization plate, the incident light I0 is shielded and an observer discriminates the condition by the dark state. When an electric field is impressed to the liquid crystal cell, the liquid crystal molecules are oriented to orient the major axis direction perpendicularly to the substrate face. The light is transmitted if the direction of polarization is parallel to the polarizing plate 1, 7. Thus, discrimination is possible because the state is lighter than the unimpressed state.
