Abstract

PURPOSE:To miniaturize a camera head part by reducing the number of components to be incorporated in the camera head part, and arranging each component in a line centering a base. CONSTITUTION:The camera head part is equipped with the base 6 in which a lens 8 is supported on one side, a solid-state image pickup element 3a and a signal processing substrate 3b fixed integrally with a holder 5 and inserted to the other side of the base 6, a cable 10 connected to the signal processing substrate 3b, a bi-sected cord clamp 4 supporting the cable 10 from both sides, and a coil spring 2 to press a holder 5 by taking reaction on the clamp 4 and to fix the solid-state image pickup element 3a and the signal processing substrate 3b on the other side. Therefore, it is possible to reduce the number of components to be incorporated in the camera head part, and to arrange each component in a line centering the base 6. In such a way, the camera head part can be miniaturized.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a compact television camera that is further miniaturized.

BACKGROUND OF THE INVENTION Conventionally, small television cameras have been divided into a camera head section and a control unit section. The camera head section has a built-in solid-state image sensor, a signal processing board, a drive circuit board, and a 7-lung back adjustment mechanism for adjusting the optical axis direction of the image sensor, which are connected to each other by respective wires and a motherboard board. has been done.

Problems to be Solved by the Invention However, the compact television camera having the above structure has a problem in that there is a limit to miniaturization because various parts are attached to the camera head.

The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a small-sized television camera that is further miniaturized.

Means for Solving the Problems In order to achieve the above object, the present invention provides a solid-state imaging system in which a camera head part is integrally fixed by a base with a lens supported on one side and inserted into the other side of the base by a holder. An element and signal processing board, a cape P connected to this signal processing board, a two-split cord clamp that grips this cable from both sides, and a reaction force to this cord clamp that presses the holder to hold the solid-state image sensor and signal. It is equipped with a coil spring that fixes the processing substrate to the other side of the base.

Function: In the compact TV camera configured as described above, the number of built-in parts in the camera head is reduced, and each part can be arranged in a line around the base, making the camera head smaller. be able to.

Embodiment Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

The compact television camera of the present invention consists entirely of a camera head section and a control unit section, and the camera head section is constructed as follows.

Reference numeral 1 in Figures 1 and 2 indicates the cable fixing ring.
Reference numeral 2 indicates a coil spring, and reference numeral 3 indicates an assembly in which the solid-state image sensor 3a and the signal processing board 3b are integrally coupled. Reference numeral 4 designates a cord clamp consisting of two parts and gripping the cable 10 to which the cable fixing ring 1 is attached from both sides to securely fix the cable 10 so that it does not shift.

A fixing ring accommodating portion 41 for accommodating the cable fixing ring 1 is formed on the inner periphery of the cord clamp 4, and a coil spring attachment portion 42 into which the coil spring 2 is inserted is formed on one side of the cord clamp 4. This coil spring mounting portion 42 is provided with a locking claw 42m that locks a holder 5, which will be described later.

Reference numeral 5 indicates a holder that supports and fixes the assembly 3, and the holder 5 includes a solid-state image sensor mounting portion 51, a signal processing board storage portion 52, a holder stop portion 53, and a coil spring contact surface 5.
4 and a locking hole 55 into which the locking claw 421 of the coil spring mounting portion 42 locks is formed, respectively.

Reference numeral 6 indicates a base, which includes a lens mounting section 61, a focus lock mounting section 62, a crystal, and a 1R fill storage section 6.
3. Cord clamp housing portions 64 are respectively formed. And numeral 7 is a focus lock ring, numeral 8
9 indicates a lens, and 9 indicates a crystal and an IR filter, respectively.

The small television camera configured as described above is assembled as follows.

Attach fixing ring 1 to cape 1v10. Pass the tip of the cable 1o through the coil spring 2 and connect it to the signal processing board 3b.
Connect to. A two-split cord clamp 4 is attached to a cable 10 with a fixing ring 1 stored in its fixing ring storage part 41, and fixed with a screw 11. Next, attach the coil panel 2 to the coil spring mounting portion 42 of the cord clamp 4.
Attach.

The assembly 3 to which the cable 10 is connected is fixed with the holder 5 divided into two parts, and the spring contact surface 5 of the holder 5 is
With the coil spring 2 in contact with the cord clamp 4, the holder 5 is locked to the coil spring attachment part 42 of the cord clamp 4. At this time, the solid-state image sensor 3a of the assembly 3 is attached to the signal processing board 3b on the solid-state image sensor mounting portion 51 of the holder 5.
are stored in the signal processing board storage section 52, respectively.

Then, the clamp 4 with the holder 5 locked is inserted into one cord clamp storage part 64 of the base 6 and fixed with the screw 12, and the crystal and IR
The filter 9 is stored, and the focus lock ring 7 and lens 8 are attached.

This reduces the number of parts built into the camera head, which in turn reduces the number of attached parts.Furthermore, it becomes possible to arrange each part in a line around the base 6, making it more compact. can be achieved.

Since the hood clamp 4 and the holder 5 are each divided into two parts and each part is sandwiched between them, installation is facilitated, and assembly workability is improved, as well as workability during maintenance and service.

The assembly 3 having the solid-state image sensor 3a is mounted on the base 6.
Since it is fixed using the elasticity of the coil spring 2, it is easy to maintain optical precision and it is possible to reliably prevent deviation of the optical axis.

In addition, since the cable is held from both sides by the cord clamp 4 which is divided into 10 cables, troubles such as breakage of the cable 10 can be prevented.

As described above, the small television camera of the present invention reduces the number of parts built into the camera head, reduces the number of attached parts, and furthermore allows each part to be assembled around the base. This allows them to be placed in a line, so
It has the advantage that it can be made smaller.
