Title: C-mos imput circuit
Inventor: AOYAMA MASAHIDE
IPC: H03K19/0175
Filed: 1990-11-29
Abstract: PURPOSE:To make an input impedance low and to reduce the affect of external noise and power consumption by connecting the gate of a MOS-type transistor connected with a resistance in parallel with the output of an invertor circuit. CONSTITUTION:The MOS-type transistor P2 connected with the resist R1 in parallel is provided and the gate of the MOS-type transistor P2 and the output of the invertor circuit are connected. Therefore, since the output terminal of the invertor becomes an 'L level' when an input is open, the P-type MOS transistor P2 becomes 'ON' and the input impedance becomes low. Since the output terminal becomes an 'H level' when the input is set in the 'L level', the P-type MOS transistor P2 becomes 'OFF', current from a power source VCC flows only from the resistance R and power consumption is reduced. Thus, when the input is open, the impedance becomes low, the effect of external noise and power consumption are reduced.

Title: Image reader
Inventor: KIMURA TETSUYA
IPC: G03B27/54
Filed: 1992-12-08
Abstract: PURPOSE:To accurately obtain reading information by image-forming focal points on the upper and lover sides of contact glass so as to set a shared focal point centering about a light source, and to form the focal point on the other side as a uniform light quantity distribution area. CONSTITUTION:It is assumed that a light source center is set as P1 and a point decided on the upper side of the contact glass 12 as P2, and a point decided on the lover side of it as P3. A reflection member 21 is comprised of an elliptical reflection member 21a setting the points P1, P2 as two focal points, and an elliptical reflection member 21b setting the points P1, P3 as the two focal points, and light converged by the reflection members 21a, 21b covers L1 to L3, respectively. The light distribution shape of the reflection member 21a is shown as in broken line where density higher than that in L1 can be obtained in L3. While, since the reflection member 21b is provided with the focal point on the lower side of the contact glass 12 differently from that of the reflection member 21a, the light distribution shape of the reflection member 21b shows a form inverted from that of the reflection member 21a, and the density high than that in L3 can be obtained in L1 as shown in alternate long and short dash line. Therefore, the dispersion of light quantity on each line can be eliminated.
