The present invention relates to a handy type sheet thickness measuring instrument, and in particular, a handy type sheet thickness measuring device that can be held by hand and accurately measures the thickness of a thick resin sheet, glass plate, metal plate, paper, carbon sheet, or the like. It is about vessels.

As a sheet thickness measuring instrument for measuring the thickness of a sheet such as a resin film or paper, a sheet thickness measuring instrument using a digital dial gauge held by hand is known (see, for example, Patent Document 1).

The sheet thickness measuring device 100 described in Patent Document 1 will be described with reference to FIGS. 13 to 16. FIG. The sheet thickness measuring instrument 100 includes a digital dial gauge 110, a holding frame 115 holding the digital dial gauge 110, a handle portion 115C provided on the holding frame 115, and an air cylinder 122. , the spindle 125 is moved upward.

The digital dial gauge 110 is fixed substantially to the upper portion of a holding frame 115. The holding frame 115 faces an upper jaw 115A formed below the digital dial gauge 110 and measures It has a lower jaw portion 115B forming a space 117 and a handle portion 115C that can be grasped by inserting the fingers of the hand into the handle space 115E. The lower jaw 115B is provided with a lower contactor 116 on which a sheet such as a resin film or paper can be placed for measurement.

The digital dial gauge 110 has a gauge body 111 having a display portion 111A on which numbers representing measured values are displayed. The gauge body 111 is provided with a spindle 125 that penetrates through the gauge body 111 and is movable in the axial direction.

An upper contact 125A is attached to the tip of the spindle 125, and when the spindle 125 descends, the upper contact 125A presses against the lower contact 116 attached to the lower jaw 115B within the measurement space 117.

Air from an air pump provided inside the holding frame 115 is supplied to the air cylinder 122 through the tube 121 . When the operation button 120 of the air pump is pressed, air is sent from the air pump to the tube 121, and the air is sent to the air cylinder 122, thereby moving the spindle 125 upward and separating the upper contact 125A from the lower contact 116. . When the operation button 120 is released, the air is released, the spindle 125 descends, and the upper contact 125A and the lower contact 116 are brought into pressure contact.

Next, a method for measuring the thickness of the sheet 140 using this sheet thickness measuring device 100 will be described.

The handle portion 115C of the holding frame 115 is gripped, and the operation button 120 is pushed by fingers. By pressing the operation button 120 with a finger, air is sent from the air pump through the tube 121 into the air cylinder 122, and the spindle 125 is lifted.

As a result, a gap is formed between the upper contact 125 A of the spindle 125 and the lower contact 116 , so that a sheet 140 such as a film is placed on the surface of the lower contact 116 in the measurement space 117 . Then, when the finger is released from the operation button 120, the air in the air cylinder 122 is released and the spindle 125 descends. As shown in FIGS. 13-15, the upper contact 125A and the lower contact 116 of the spindle 125 sandwich the sheet 140 therebetween. The dimension at this time is displayed on the display portion 111A, and the thickness of the sheet 140 is measured. By reading the dimensions at this time, the thickness of the sheet 140 is measured.

Utility Model Registration No. 3206532

By the way, if the sheet 140 is thick and stiff, the thickness of the sheet 140 may not be measured accurately. That is, as shown in FIG. 16, with the sheet 140 mistakenly placed obliquely on the lower contactor 116, the finger is released from the operation button 120 and the spindle 125 is lowered. At this time, if the sheet 140 is stiff, the sheet 140 is not securely sandwiched between the upper contactor 125A and the lower contactor 116, and the sheet 140 is sandwiched in an oblique state. . As a result, the thickness is measured with the sheet 140 tilted, and a gap exists between the lower contactor 116 and the sheet 140, making it impossible to measure the thickness accurately.

The upper contactor 13 is positioned between the left and right upper pressing rollers 42 and 42 and the lower contactor 14 is positioned between the lower support rollers 32 and 32 . The sheet 60 is pressed by the upper pressing rollers 42, 42 and the lower supporting roller 32 in the vertical direction, and the sheet 60 is arranged between the upper contact 13 and the lower contact 14 without being tilted. become. As a result, even if the sheet 60 is stiff, the sheet 60 can be accurately positioned between the upper contactor 13 and the lower contactor 14, so that the thickness of the sheet 60 can be accurately measured. can be done.

Also, in this embodiment, since the upper pressing rollers 42, 42 and the lower supporting rollers 32, 32 are rotatable, the sheet 60 sandwiched between the two rollers can be slid. By sliding the sheet 60 with the upper contactor 13 in contact with it, the thickness of the sheet 60 can be easily measured continuously.

In the above-described embodiment, the lower support rollers 32, 32 as the lower support members, the upper pressing rollers 42, 42 as the upper support members, and the support members are composed of rollers. 60 may be configured to be pressed from both sides. With such a configuration, the thickness can be accurately measured even for a stiff sheet 60 . Since it is a non-rotating member, it is difficult to slide the sheet 60, so it is not suitable for continuous sheet 60 measurement.

It should be considered that the embodiments disclosed this time are illustrative in all respects and not restrictive. The scope of the present invention is indicated by the scope of the claims rather than the description of the above-described embodiments, and is intended to include all modifications within the meaning and scope equivalent to the scope of utility model registration claims. .
