The release member pressing portion 212 is configured by an elastic member, and the release member 210 is formed to be biased toward the operation button 40 via the release member pressing portion 212. The biosensor protrusion member expansion gear (gear) 116 operates so that the operation button 40 can slide when the release member 210 is pushed into the back surface of the operation button 40. The pressure spring 108 applies pressure to the sealing rollers 105 a and 105 b that press the cartridge case 110. In addition, about another structure, the same site | part as FIG.1 and FIG.2 attaches | subjects the same code | symbol, and abbreviate | omits description.

Operation buttons for sending out biosensors one by one from the thus configured biosensor dispensing apparatus will be described with reference to FIGS. 5 and 6.
A release member 210 for releasing the operation of the safety mechanism against an inadvertent operation is placed on the operation button 40 in the vicinity of or inside the operation button 40 which is an operation unit interlocked with the biosensor protruding member 48. Provided in the recess 213 for pressing. When the release member 210 is pushed in, the release member 210 can be slid with respect to the back surface of the operation button 40 when the operation button 40 slides or rotates by being submerged after being pushed into the back surface of the operation button 40. And is pushed toward the operation button 40 so as to be pushed back by the release member pressing means 212 formed of an elastic member at the pushed position. When the operation button 40 returns to the initial position after the series of operations is completed, if the user lifts the finger from the operation button 40, the release provided in the recess 213 formed in the operation button 40 is performed. The release member 210 protrudes from the viewing window 211 of the member 210 and returns to the home position.

  Further, the operation button 40 is interlocked with the biosensor ejecting member 48 and forms a part of a gear mechanism such as a gear or a rack for moving the biosensor ejecting member 48. As shown in FIG. When the member 210 is pushed, one end of the sealing roller elevating member 103 and one end of the release member 210 come into contact with each other, and then rotate around the fulcrum. The sealing roller locking member 102 locked to the other end of the sealing roller lifting / lowering member 103 performs the lifting / lowering operation, so that the sealing rollers 105a and 105b move upward, and the biosensor ejection port 140, And the opening / closing operation | movement of the biosensor protrusion member inlet 141 is attained.

  Thus, according to the biosensor cartridge according to the second embodiment and the biosensor dispensing apparatus to which the biosensor cartridge is attached, the operation button interlocked with the biosensor ejecting means for pushing out the biosensor is integrated with the safety mechanism including the release member. In order to prevent the biosensor from protruding due to inadvertent operation, the biosensor is sequentially sent out by the operation button integrated with the safety mechanism, and the used sensor is returned to perform return operation. Can be eliminated cleanly.

  Further, since the release member is provided in the recess formed in the operation button part, the release operation of the safety mechanism can be easily performed in the measurement operation.

  In addition, the release member slides on the back surface of the operation button part via a pressing member configured by an elastic member that urges the apparatus to the outside, and thus the posture of the release member after the operation button part slides is locked. By using the shape of the existing operation button without requiring a mechanism, a reliable operation can be performed.

  In addition, the operation button is configured to form a part of a gear mechanism such as a gear or a rack for moving the biosensor protrusion member in conjunction with the biosensor protrusion member. In addition, the biosensor protruding means can be shared.

  In addition, since the release member operates in conjunction with the sealing roller suspension member, it is possible to reliably release the sealing roller from the biosensor ejecting port and the biosensor ejecting member entrance. Removal can be made possible.

  From FIG. 8, the biosensor positioning ribs 111a to 111f are formed on the inner wall of the cartridge case 110 and determine the position when the biosensor 46 is stored. The cartridge bottom surface rib 155 is a rib formed on the bottom surface of the cartridge case 110, and determines the position when the biosensors are stacked. In addition, about another structure, the same site | part as FIG.3 and FIG.4 attaches | subjects the same code | symbol, and abbreviate | omits description.

The operation of the thus configured cartridge case will be described with reference to FIG.
As shown in FIG. 8A, when the biosensor 46 is stacked and stored in the cartridge case 110, the storage position can be roughly determined by the biosensor positioning rib 111. Among the biosensor positioning ribs 111, the height b of the rib of the biosensor positioning rib 111f provided on the inner wall on the biosensor ejection port 140 side and the biosensor positioning rib provided on the inner wall on the biosensor ejection member inlet 141 side The ribs 111b have different heights c.

In order to prevent a part of the biosensor 46 from coming into contact and keep the frictional force against the operation of the biosensor 46 low, only the apex of the biosensor positioning rib 111f is stored when the biosensor 46 is stored in the cartridge case 110. Need to be in contact with. As a countermeasure, by setting Lc> Ls, a> b, c> a, and (Lc + b + c)> (Ls + a), any part of the outer periphery of the biosensor 46 can contact only the biosensor positioning rib 111. .

  Further, the outer peripheral portion of the biosensor 46 is accommodated in the cartridge 110 so as not to contact the inner wall portion of the inner wall surface of the cartridge case 110 other than the surface on which the biosensor positioning ribs 111f and 111b are formed. Two biosensor positioning ribs 111c and 111d or 111a and 111e were provided on the inner wall surface corresponding to the side surface in the longitudinal direction of the biosensor 46, respectively.

  Further, as shown in FIG. 8C, cartridge bottom ribs 155 are provided at both ends of the bottom of the opening of the cartridge case 110 that receives the stacked biosensors 46, and the height of the cartridge bottom rib 155 is set so as to project the biosensor. It formed so that it might become smaller than the thickness of a member. Further, the distance between the cartridge bottom ribs 155 provided at both ends was formed to be larger than the width of the biosensor protruding member.

  As described above, according to the biosensor cartridge according to the fourth embodiment and the biosensor dispensing apparatus to which the biosensor cartridge is attached, the ribs are formed on the inner wall of the biosensor cartridge. Smooth sliding operation is possible.

  Also, among the ribs formed on the inner wall of the biosensor cartridge, the height of the rib formed on the inner wall on the rear end side of the biosensor is formed to be higher than the height of the rib formed on the inner wall on the test end side. And since the recessed part was formed in the rear-end side of a biosensor, loading of a biosensor can be facilitated and erroneous loading can be prevented.

  In addition, the height of the rib formed on the inner wall of the biosensor cartridge may be set arbitrarily. By setting in this way, erroneous loading when the biosensor is loaded into the biosensor cartridge can be prevented. The frictional force with respect to the sliding operation of the sensor can be kept low.

  In addition, although two ribs are formed on the inner wall surface corresponding to the side surface in the longitudinal direction of the biosensor cartridge, the number of ribs can be arbitrarily set to at least two or more. By doing so, it is possible to prevent erroneous loading when loading the biosensor into the biosensor cartridge.

  In addition, since the height of the rib provided on the bottom surface of the biosensor cartridge is made smaller than the thickness of the biosensor protruding member, the biosensor can be reliably protruded from the biosensor cartridge one by one.

  In addition, since the distance between the ribs provided at both ends of the bottom surface of the opening of the biosensor cartridge is made larger than the width of the biosensor ejecting member, the biosensor cartridge does not strike the biosensor cartridge. It is possible to reliably project the biosensor arranged on the bottom surface of the.
