Description

  The present invention relates to a lens operating device, and more particularly to a lens operating device that controls a driving system of a zoom lens by a rotating operation.

  Conventionally, in a television camera lens, a photographer uses a lens operation device to perform a zoom operation. This lens operation device has an operation member for a photographer to manually operate. An angle signal is obtained from an angle sensor attached to the rotation shaft of the operation member by rotating the operation member in the tele direction and the wide direction from the neutral point of the rotation range. If the obtained angle signal is the neutral point of the operation member, the zoom drive signal is not output. If an angle signal in the tele direction or wide direction other than the neutral point is obtained, the zoom drive speed can be adjusted in the tele direction or wide direction according to the angle via a drive device such as a motor in a TV camera lens. Control. A configuration in which the operation member always returns to the neutral point by the elastic member, the cam member, and the sliding member engaged with the cam member so that the angle signal is not generated when the operation member is tilted when the photographer does not operate.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. 1 to 16 show a lens operating device according to an embodiment of the present invention.

  The lens operating device according to the first embodiment of the present invention will be described below with reference to FIGS.

  Based on FIG. 1, the angle detection structure by the operation member 1 is demonstrated.

  The lens operating device of the present invention is a lens operating device for operating an operation target such as a lens of the lens device, has a rotating operation member, and gives a command value to the lens device according to the operation angle of the operation member. It is a lens operating device that operates a desired operation target by outputting.

  The operation member 1 is attached to the rotary shaft 4 via the top 3 with a screw 2. The rotating shaft 4 is rotatably attached to the casing cylinder 5 via bearings 6 and 7 provided on the casing cylinder 5. An angle sensor (angle detector) 9 is fixed to the casing cylinder 5 via a sheet metal 8. The sensor shaft 9 a of the angle sensor 9 is an axis that detects an angle by rotating, and the sensor shaft 9 a is fixed to the rotating shaft 4. A substrate 11 is fixed to the housing cylinder 5 via a lid member 10. A signal line from the angle sensor 9 is connected to a lens device (not shown) through the substrate 11. In such a structure, when the operation member 1 is rotated, the sensor shaft 9a rotates via the rotation shaft 4, so that the rotation angle signal of the operation member 1 is detected. Based on the detected angle signal, the zoom unit of the lens device is driven.

  Based on FIGS. 1 to 5, a structure in which the operation member 1 in the speed control mode returns to a predetermined return position and a structure in which an operation feeling occurs when the operation member 1 is operated will be described.

  The switching member (switching means) 12 is held by the retaining ring 14 via the cover 13 and the housing cylinder 5 so as to be slidable with respect to the housing cylinder 5. The switching cylinder 15 is held rotatably with respect to the casing cylinder 5 by the casing cylinder 5 and the presser ring 16.

  As shown in FIG. 3A, in the speed control mode, the photographer places the indicator 12a of the switching member 12 on the SPEED side printed on the cover 13. Then, as shown in FIGS. 2 (a) and 4, the pin portion (switching means) 12 b of the switching member 12 engages with the rotation restricting groove portion 15 a of the switching cylinder 15, and the switching cylinder 15 rotates with respect to the casing cylinder 5. Be regulated. In a state where the switching member 12 is positioned so that the index 12a is on the SPEED side printed on the cover 13, the return function is in an effective state (effective state) as described below.

  A cam roller (cam follower) 17 fixed to the rotating shaft 4 and a cam groove 18a provided in the slide cam 18, a linear motion roller 19 fixed to the slide cam 18 and a straight groove 15b provided in the switching cylinder 15 are associated with each other. Match. The casing cylinder 5 is attached with a cover 13 and a lid 20 provided with a screw portion 20a on the inner diameter. The lid 20 is provided with a spring receiver 21 having a screw portion 21a that engages with the screw portion 20a. The spring receiver 21 is connected and fixed by an adjustment knob 22 and a screw 23. Then, by rotating the adjustment knob 22, the spring receiver 21 can be screwed. A compression coil spring (elastic member) 24 that is always pressed is provided between the slide cam 18 and the spring receiver 21.

  In such a structure, when the photographer is not touching the operation member 1 as shown in FIGS. 4A and 5A, the switching cylinder 15 is moved by the compression coil spring 24 by the linear motion roller 19 and the straight groove 15b. On the other hand, the cam groove 18 a of the slide cam 18 whose rotation coaxial with the rotary shaft 4 is restricted pushes the cam roller 17. Then, the rotating shaft 4 is held so that the cam roller 17 and the cam groove 18a are in a stable position. As a result, the operating member 1 returns to the neutral point (return position). Next, when the photographer rotates the operation member 1 as shown in FIGS. 4B and 5B, the cam roller 17 moves only in the rotational direction while engaging the cam groove 18a, and the slide cam 18 The compression coil spring 24 is further pushed along the groove 18a. Since the photographer feels the repulsive force received by pressing the compression coil spring 24, this is the photographer's operational feeling. Here, when the photographer releases his / her hand from the operation member 1, as described above, the operation member 1 is neutral (returned position) by the applied elastic force as shown in FIGS. 4 (a) and 5 (a). ) Return to the return state. In addition, since the spring receiver 21 is screw-fed by rotating the adjustment knob 22, the pressing force of the compression coil spring 24 can be changed, that is, the photographer's operational feeling can be changed. Become. Based on FIGS. 1 to 3 and FIGS. 6 to 7, a structure in which the operation member 1 in the position control mode is held at the operation position of the photographer and a structure in which an operation feeling is generated when the operation member 1 is operated. explain.

  As shown in FIG. 3B, in the position control mode, the index 12a of the switching member 12 is arranged by the photographer on the POSITION side printed on the cover 13. Then, as shown in FIG. 2B and FIG. 6, the pin portion 12 b of the switching member 12 is disposed on the restriction release groove portion 15 c side of the switching cylinder 15, and the switching cylinder 15 is in the restriction release groove portion 15 c with respect to the housing cylinder 5. Can be rotated coaxially with the rotary shaft 4 within the open range. In a state where the switching member 12 is positioned so that the index 12a is on the POSITION side printed on the cover 13, the return function is in an invalid state (invalid state) as described below.

  In such a structure, when the photographer is not touching the operation member 1 as shown in FIGS. 6A and 7A, the cam groove 18 a of the slide cam 18 contacts the cam roller 17 by the compression coil spring 24. Touched and pressed. As a result, the rotation position (angle) of the operation member 1 connected to the cam roller 17 via the rotation shaft 4 is maintained by the frictional force between the compression coil spring 24 and the slide cam 18 or the spring receiver 21. Next, when the photographer rotates the operation member 1 as shown in FIGS. 6B and 7B, the switching cylinder 15 is rotatable with respect to the casing cylinder 5, so that the rotation shaft 4 and the slide cam 18 and the switching cylinder 15 are all rotated together. At this time, the compression coil spring 24 and the slide cam 18 or the spring receiver 21 (rotational load mechanism) slide, and the photographer feels the dynamic frictional force received from the compression coil spring 24, which becomes a load with respect to the rotation. Become. Here, when the photographer releases his / her hand from the operation member 1, the operation member 1 is held by the frictional force between the compression coil spring 24 and the slide cam 18 or the spring receiver 21 as described above. The operation state of FIG. 5B is maintained. In addition, since the spring receiver 21 is screw-fed by rotating the adjustment knob 22, the pressing force of the compression coil spring 24 can be changed, that is, the photographer's operational feeling can be changed. Become.

  As described above, in the lens operating device of the present invention, the compression coil spring 24, the cam groove 18a, and the cam roller 17 are elastically set to the stable position with the predetermined position of the rotation range of the operating member 1 as the stable position. The return mechanism is configured to return by force. Here, in this embodiment, the cam roller 17 is fixed to the rotating shaft 4 and the cam groove 18a is formed on the slide cam 18 side, and receives the force in the direction of pressing in the axial direction. The configuration is not limited. For example, even if the cam groove 18a is fixed to the rotating shaft 4 and the cam roller 17 is configured on the slide cam 18 side, the effect of the present invention can be enjoyed.

  Based on FIGS. 1-2, the operation | movement at the time of mode detection of speed control mode and position control mode is demonstrated.

  The slide member 25 is slidably held with respect to the casing cylinder 5 by engaging with the switching member 12. A contact 26 is fixed to the slide member 25. On the other hand, a mode detector 27 connected to the substrate 11 is fixed to the housing cylinder 5. The contact between the contact 26 and the mode detection unit 27 makes it possible to detect switching between the speed control mode and the position control mode. Further, a display unit 28 for visually recognizing the mode is fixed to the casing cylinder 5, and the display unit 28 is connected to the substrate 11.

  A control method at the time of switching between the speed control mode and the position control mode will be described based on the flowchart of FIG.

  In STEP1, it is determined whether the switching member is in the speed control mode. If it is the speed control mode, the process proceeds to STEP2. If it is the position control mode, the process proceeds to STEP6. In STEP2, the mode is set to speed control. In STEP 3, the display unit is turned off to inform the photographer that the speed control mode is set. In STEP 4, the angle of the operation member operated by the photographer is detected. In STEP 5, the zoom speed of the lens device is controlled based on the detected angle ΔZ. In STEP 6, the speed control signal given to the zoom of the lens apparatus is set to 0, and the zoom is not moved by the operation member. Thereafter, the position control mode is being initialized until the transition to the position control mode in STEP 11 is completed, and the lens operation device controls the operation target in the position control mode until a predetermined condition described below is satisfied. (Operation) cannot be performed. In STEP 7, the display unit blinks to notify the photographer that the position control mode is being initialized. In STEP 8, zoom position information (lens position) z on the lens device side is acquired by a lens position acquisition unit (not shown). In STEP 9, the angle detection information Z of the operating member of the lens operating device is acquired. In STEP 10, if the operation member is operated by the photographer and the zoom position information z and the angle detection information Z coincide (when z = Z), the position corresponding to the angle detection information of the operation member 1 and the zoom position information z (If is matched), go to STEP11. If the zoom position information z and the angle detection information Z do not match (unless z = Z) (if the position corresponding to the angle detection information of the operation member 1 and the zoom position information z do not match), go to STEP1. Return. In STEP 11, the mode is set to the position control mode. In STEP 12, the display unit is turned on to notify the photographer that the initialization of the position control mode is completed and the position control mode is started. In STEP 13, the zoom position of the lens apparatus is controlled so as to maintain the relationship of z = Z. In STEP14, it is determined again whether the switching unit is in the speed control mode. If the speed control mode, the process proceeds to STEP2, and if it is the position control mode, the process proceeds to STEP13.

  This control can prevent unnatural driving unintended by the photographer even immediately after shifting from the speed control mode to the position control mode. With the above structure, it is possible to switch between the speed control mode and the position control mode with a single lens operation device, and when the mode is switched, it is possible to switch to an operation mode suitable for each control mode.

  Further, since the operational feeling of the two modes can be changed with one compression coil spring, the size and cost are reduced.

  Furthermore, since the initialization operation is performed when switching from the speed control mode to the position control mode, it is possible to prevent a zoom malfunction at the time of switching unexpected by the photographer.

  A lens operating device according to the second embodiment of the present invention will be described below with reference to FIGS.

  Based on FIG. 9, the angle detection structure by the operation member 31 is demonstrated.

  The operation member 31 is attached to the rotary shaft 34 by a screw 32 via a frame (frame member) 33. The rotating shaft 34 can be rotated with respect to the casing cylinder 35 by being attached via bearings 36 and 37 provided on the casing cylinder 35. An angle sensor 39 is fixed to the casing cylinder 35 via a sheet metal 38. A sensor shaft 39 a that detects an angle by rotation provided in the angle sensor 39 is fixed to the rotation shaft 34. A substrate 41 is fixed to the housing cylinder 35 via a lid member 40. The angle sensor 39 is connected to a lens device (not shown) through the substrate 41. In such a structure, when the operation member 31 is rotated, the sensor shaft 39a rotates via the rotation shaft 34, and thus the rotation angle signal of the operation member 31 is detected. The zoom unit of the lens device is driven by the detected angle signal.

  A structure in which the operating member 31 returns to the neutral point (return position) in the speed control mode and a structure in which an operational feeling is generated when the operating member 31 is operated will be described based on FIGS.

  The switching member 42 is slidably held with respect to the casing cylinder 35 by a retaining ring 44 through the cover 43 and the casing cylinder 35. Further, the switching cylinder 45 is held by the casing cylinder 35 and the presser ring 47 via the compression coil spring 46 so as to be rotatable with respect to the casing cylinder 35.

  As shown in FIG. 11A, in the speed control mode, the photographer places the indicator 42a of the switching member 42 on the SPEED side printed on the cover 43. Then, as shown in FIGS. 10A and 12, the pin portion 42 b of the switching member 42 engages with the rotation regulating groove 45 a of the switching cylinder 45, and the rotation of the switching cylinder 45 with respect to the housing cylinder 35 is regulated.

  The rotary piece 48 is held to be rotatable about the shaft 49 with respect to the switching cylinder 45 via the shaft 49. A cam roller 50 is attached to the rotating piece 48, and the cam roller 50 and a cam groove 34a provided in the rotating shaft 34 are engaged. The casing cylinder 35 is provided with a cover 43 and a lid 51 having an inner diameter provided with a screw portion 51a. The lid 51 is provided with a spring receiver 52 having a screw portion 52a that engages with the screw portion 51a. The spring receiver 52 is connected and fixed by an adjustment knob 53 and a screw 54. Then, by rotating the adjustment knob 53, the spring receiver 52 can be screwed. A compression coil spring 55 that is always pressed is provided between the rotary piece 48 and the spring receiver 52 via a collar member 56.

  In such a structure, when the photographer is not touching the operation member 31 as shown in FIGS. 13A and 14A, the rotary piece 48 is pushed by the compression coil spring 55 via the collar member 56. Then, since the cam roller 50 provided in the rotary piece 48 pushes the cam groove 34a, the rotating shaft 34 is held so that the cam roller 50 and the cam groove 34a are in a stable position. As a result, the operation member 31 is in the return state. Next, when the photographer rotates the operation member 31 as shown in FIGS. 12B and 13B, the cam roller 50 rotates around the shaft 49 while engaging with the cam groove 34a. . That is, the rotary piece 48 further pushes the compression coil spring 55 via the collar member 56 along the cam groove 34a. Since the photographer feels the repulsive force received by pressing the compression coil spring 55, it becomes a load with respect to rotation, which is an operational feeling for the photographer. Here, when the photographer releases his / her hand from the operation member 31, as described above, the operation member 31 returns to the return state as shown in FIGS. 12 (a) and 13 (a). Further, since the spring receiver 52 is screw-fed by rotating the adjustment knob 53, the pressing force of the compression coil spring 55 can be changed, that is, the photographer's operational feeling can be changed. Become.

  Based on FIGS. 9 to 11 and FIGS. 14 to 15, a structure in which the operation member 31 in the position control mode is held at the operation position of the photographer and a structure in which an operation feeling is generated when the operation member 31 is operated. explain.

  As shown in FIG. 11B, in the position control mode, the index 42a of the switching member 42 is arranged on the POSITION side printed on the cover 43 by the photographer. Then, as shown in FIGS. 10B and 14, the pin portion 42 b of the switching member 42 is disposed on the restriction release groove 45 b side of the switching cylinder 45, and the switching cylinder 45 can rotate with respect to the casing cylinder 35. .

  In such a structure, when the photographer is not touching the operation member 31 as shown in FIGS. 14A and 15A, the compression coil spring 55 pushes the rotary piece 48 through the collar member 56. Then, the cam roller 50 provided on the rotary piece 48 pushes the rotary shaft 34 through the cam groove 34a. As a result, the operation member 31 is held by the frictional force between the collar member 56 and the rotary piece 48. Next, when the photographer rotates the operation member 31 as shown in FIGS. 14B and 15B, the switching cylinder 45 can be rotated with respect to the housing cylinder 35. 48 and the switching cylinder 45 are all rotated together. At this time, the collar member 56 and the rotating piece 48 slide, and the photographer feels this dynamic frictional force, which is an operational feeling. Here, when the photographer releases his / her hand from the operation member 31, as described above, the operation member 31 is held by the frictional force between the collar member 56 and the rotary piece 48, and thus FIGS. 14B and 15. The operation state of (b) is maintained. Further, since the spring receiver 52 is screw-fed by rotating the adjustment knob 53, the pressing force of the compression coil spring 55 can be changed, that is, the photographer's operational feeling can be changed. Become.

  Based on FIGS. 9 to 10 and FIG. 16, the operation at the time of mode detection of speed control and position control will be described.

  The slide member 57 is slidably held with respect to the casing cylinder 35 by engaging with the switching member 42. A contact 58 is fixed to the slide member 57. On the other hand, a mode detector 59 connected to the substrate 41 is fixed to the housing cylinder 35. Contact between the contact 58 and the mode detector 59 makes it possible to detect switching between speed control mode and position control mode. Further, a display unit 60 for visually recognizing the mode is fixed to the casing cylinder 35, and the display unit 60 is connected to the substrate 41. In addition, the slide member 57 is provided with an index portion 57a which is a scale. Then, the indicator 57a cannot be visually recognized by the photographer in the speed control mode as shown in FIG. 16A, but can be visually recognized by the photographer in the position control mode as shown in FIG. 16B. As a result, only in the position control mode, the photographer can visually recognize the amount of rotation operation of the operation member 31 by combining the index portions 31a and 57a provided on the operation member 31.

  Since the control method at the time of switching between the speed control and the position control is the same as that in the first embodiment, a description thereof will be omitted.

  With the above structure, it is possible to switch between the speed control mode and the position control mode with a single lens operating device, and when the mode is switched, it is possible to switch to an operation mode suitable for each control mode.

  Further, since the operational feeling of the two modes can be changed with one compression coil spring, the size and cost are reduced.

  Furthermore, since the index can be visually recognized by the photographer only in the position control mode, it is possible to improve the operability of the photographer during position control without impairing the operability during speed control.
