Abstract
Abstract A video system comprising a video camera and a recording device to record video signals obtained by the video camera. The recording device includes a video tape recorder (VTR) which may be combined with the video camera when recording and otherwise may be combined with a reproduction unit. Mode switches in the VTR are changed over depending on the combination desired. When the VTR is used with the camera, the combination records sound, video signal and controls signals on a tape wound around a drum. A system control circuit controls various motors and solenoids control operation of the VTR. Power supply to the system is controlled by a power source switch in the VTR, which element provides "OFF", "STANDBY I" and "STANDBY II" modes. Delay elements operate in the two standby modes. When the power source switch is in either standby mode, loading is done automatically. One standby mode provides power to a rotating system and the other mode provides no power. The delay elements provide different delay times for each mode so that triggering of the camera can be made with due consideration for the start up time of the rotating system. The built-in delays are effective in conserving power.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
271 words
An information signal recording apparatus, comprising: (a) a rotary head for recording information signals on a tape-shaped recording medium; (b) a cylindrical member for supporting the rotary head, said cylindrical member having a peripheral surface; (c) a head driving motor for rotating the rotary head at a predetermined speed; (d) tape loading means for shifting the tape-shaped recording medium between a first position in which said medium does not contact the peripheral surface of the cylindrical member, and a second position in which said medium is aligned with the peripheral surface; (e) a power source for generating electrical power; (f) a power switch which can be changed over between a first condition and a second condition by one stroke of a manual operation and supplies said electrical power to said head driving motor and said tape loading means when it is in the first condition, and does not supply the electrical power to said head driving motor and said tape loading means when it is in the second condition, said power switch being directly connected to said power source; (g) a trigger switch operated by a manual operation for instructing a recording start by said rotary head, said trigger switch being invalid while said power switch is in said second condition; and (h) a control circuit responsive to the manual operation for changing over said power switch from said second condition to said first condition, for controlling said head driving motor and said tape loading means, so that said rotary head rotates at the predetermined speed and the tape-shaped recording medium is shifted from the first position to said second position.
Claim 2
Dependent Claim
271 words
An information signal recording apparatus, comprising: (a) a rotary head for recording information signals on a tape-shaped recording medium; (b) a cylindrical member for supporting the rotary head, said cylindrical member having a peripheral surface; (c) a head driving motor for rotating the rotary head at a predetermined speed; (d) tape loading means for shifting the tape-shaped recording medium between a first position in which said medium does not contact the peripheral surface of the cylindrical member, and a second position in which said medium is aligned with the peripheral surface; (e) a power source for generating electrical power; (f) a power switch which can be changed over between a first condition and a second condition by one stroke of a manual operation and supplies said electrical power to said head driving motor and said tape loading means when it is in the first condition, and does not supply the electrical power to said head driving motor and said tape loading means when it is in the second condition, said power switch being directly connected to said power source; (g) a trigger switch operated by a manual operation for instructing a recording start by said rotary head, said trigger switch being invalid while said power switch is in said second condition; and (h) a control circuit responsive to the manual operation for changing over said power switch from said second condition to said first condition, for controlling said head driving motor and said tape loading means, so that said rotary head rotates at the predetermined speed and the tape-shaped recording medium is shifted from the first position to said second position.
Claim 3
Dependent Claim
80 words
An apparatus according to claim 1, and further comprising a capstan for transporting said tape-shaped recording medium, a capstan driving motor for rotating the capstan, and a pinch roller movable for engaging said tape-shaped recording medium with the capstan to transport said tape-shaped recording medium, said control circuit further controlling said capstan driving motor to rotate at a predetermined speed in response to the manual operation for changing over said power switch from said second condition to said first condition.
Claim 4
Dependent Claim
37 words
An apparatus according to claim 2, wherein said control circuit further controls said pinch roller to engage said tape-shaped recording medium with the capstan in response to the instruction of the recording start by said trigger switch.
Claim 5
Dependent Claim
