Filed: 1987-08-26
Abstract: PURPOSE:To enable the replacement of paper to be more easily performed by constituting a device of a drawer frame provided so as to be stopped to a fixed frame, extruding member and a stop releasing member. CONSTITUTION:For the replacement of paper, a stopper member 50 is released by actuating a stop releasing member 54. Then a drawer frame 12 is placed in a condition drawable for a fixed frame 3. Consequently, the drawer frame 12 is pushed out from the fixed frame 3 by an extruding member 47, that is, the drawer frame 12 pulls its front surface side from a takeout port 8 of the fixed frame 3. As the result, a paper storage part of the drawer frame 12 is drawn out from the fixed frame 3. Under this condition, paper is stored in the paper storage part. When storage is finished, by pressing the front surface of the drawer frame 12 with a finger tip or the like, the drawer frame 12 is returned into a storage chamber 9 of the fixed frame 3. Under this condition, the drawer frame 12 is stopped to the fixed frame 3 by actuating the stopper member 50.

Abstract: PURPOSE:To prevent the sense of incongruity caused by the change of a viewing angle from being given by setting a target focal distance to a prescribed focal distance based on a present focal distance just before zooming in the case that a focus is repeatedly detected while zooming is executed to a wide side when the focus cannot be detected. CONSTITUTION:When a focus detection start switch is turned on, the focus is detected by a range-finding part 2. In the case that the focus cannot be detected as the result, the focus is repeatedly detected while the zooming is executed toward the target focal distance set based on the present focal distance at that time by a zoom lens LA. At this time, the focal distance which is shorter than the present focal distance just before the zooming and which obtains the viewing angle to such an extent that the sense of the incongruity is not given to the viewing angle at the present focal distance is selected as the target focal distance. Thus, the sense of the incongruity is not given to a photographer by the change of the viewing angle and the focus is detected within a fixed range even in the case of a photographing situation that the focus cannot be detected up to the present.

Title: Protecting circuit for n-channel mos type output driver
Inventor: WAKIMOTO YASUHIRO
IPC: H03K19/003
Filed: 1981-12-29
Abstract: PURPOSE:To prevent the thermal breakdown of an output transistor at the time of shortcircuiting the output of an output driver by forming a control circuit which shields the first MOS transistor when the level of the output terminal decreases lower than the prescribed value. CONSTITUTION:When ''H'' is applied to a control signal X, ''L'' is applied to a control signal-X, and ''H'' is outputted at the output OUT, it is assumed that the output OUT is shortcircuited to the ground side. Since the voltage of the output OUT decreases at this time, a transistor TS1 is turned ON, thereby causing a transistor TS2 to be turned ON. Accordingly, a current path is formed from the control signal X through the transistors TS2, TS1 to the output OUT, the voltage of the control signal X is compulsorily drawn to the ''L'', thereby causing the output transistor TO1 to be turned OFF, thereby breaking the output.
